Alfa Romeo Giulia GTAm 2021 review

A new GTA model wouldn’t be true to its name without some exotic weight-saving measures, and they’re present in abundance. Along with most of the additional body parts, the bonnet, front wings and roof are all made of carbonfibre. 

At 100kg, the overall weight saving isn’t quite as significant as you might expect. Still, the 1580kg Giulia GTA is lighter than the Audi RS5 (by 147kg), the BMW M3 Competition (by 170kg) and the Mercedes-AMG C63 S 4Matic+ (also by 170kg). 

The more hardcore Giulia GTAm takes the savings a step further with lightweight plastic rear door panels, polycarbonate rear windows, Sabelt carbonfibre-shell front seats, nylon door pulls in place of the standard handles and the removal of the rear seating. Even with the addition of a rear roll cage, Alfa Romeo says these measures trim a further 40kg from the kerb weight, taking it down to 1540kg.   

Under the lightweight bonnet, the Giulia GTA uses the same Ferrari-designed and -developed turbocharged 2.9-litre V6 petrol engine as the Giulia Quadrifoglio. Power is up by 30bhp to 533hp through the adoption of new conrods, additional oil injectors, a revised oil cooler, tweaks to the software controlling the turbocharger and, most obvious of all, an Akrapovic titanium exhaust system featuring twin centrally mounted tailpipes. Torque, however, remains the same at 443lb ft.

Drive is sent to the rear wheels via a ZF-produced eight-speed gearbox and electronically controlled differential, both of which receive unique mapping specific to the new headlining Giulia model.

Further changes are focused on the Giulia GTA’s chassis. It receives tracks that are 25mm wider at the front and 50mm wider at the rear, together with new mapping for the electromechanical steering and a lowered double-wishbone front and multi-link rear suspension with firmer springs and dampers as well as beefed-up anti-roll bars, among other detailed changes. Bespoke 20in forged alloy wheels with a centre-locking nut wear Michelin Pilot Sport Cup 2 tyres, 265/30 ZR20 up front and 285/30 ZR20 at the rear.
